Step-by-step explanation:

I assume that this is asking you to write the simplest equation.

The three formulas you need are the slope formula, the point-slope formula and the linear equation.

Slope formula is $\frac{y2-y1}{x2-x1}$ , Point slope is y-y1=m(x-x1), where m is the slope and y1 and x1 come from a point, and linear equation is y=mx+b. Where m is the slope, and b is the y-intercept.

1)Slope=3, and y-intercept=-1, so y=3x-1

2)Slope=-1/5, and y-intercept=4, so y=-1/5x+4

3)Slope=5, and it goes through the point (2,7), so y-7=5(x-2) you distribute the 5 to get y-7=5x-10, and you add the 7 to get y by itself to get y=5x-3

4)Slope=0, and it goes thorough point (-3,3), so y-3=0(x+3). Distribute the zero to get y-3=0. Add thee to get y by itself to get y=3

5)slope=3/4, and it goes through point (0,6), so (0,6) shows that the y-intercept=6. y=3/4x+6

6)Goes through points (6,2) and (5,4), so you use the slope formula to get $\frac{4-2}{6-5}=\frac{2}{1}=2$. y-2=2(x-6), and you distribute the 2 to get y-2=2x-12. Add two to get y by itself, and you get y=2x-10.

7) Goes through (0,4) and (2,7). Slope formula $\frac{7-4}{2-0}=\frac{3}{2}$. (0,4) shows the y-intercept=4. y=3/2x+4.

8)Goes through points (-3,2) and (8,2). Slope formula $\frac{2-2}{8-(-3)}=\frac{0}{8+3}=0$. Point-slope to get y-2=0(x-3). Distribute 0 to get y-2=0. Add 2 to get y by itself to get .

9)Goes through points (-6,1) and (-3,2). Slope formula $\frac{2-1}{-3-(-6)} =\frac{1}{-3+6} =\frac{1}{3}$ . Point-slope to get y-1=1/3(x+6). Distribute 1/3 to get y-1=1/3x+2. Add 1 to get y by itself to get $y=\frac{1}{3}x+3$.

10)y-intercept=4 and goes through point (2,3). Turn y-intercept into point (0,4). Slope formula. $\frac{3-4}{2-0}=\frac{-1}{2}$ . With y-intercept=4, $y=\frac{-1}{2}x+4$
